Specification of Letters Patent.

To-aZl whom it may concern:

Be it known that I, AUGUST O. KRononR, a citizen of the United States,residing at 7 45 Hubbard v street, Milwaukee, in the county of Milwaukeeand State of (Viscousin, have invented anewand useful Storage- Cell, ofwhich .the following is a specification.

My invention relates to storage cells, by means of whichas commonlyunderstoodelectrical energy is stored for future use.-

The objects are, to furnish a storage cell of higher efliciency andgreater power, but less liable to injurious chemical action, than Toattain these objects I use antimony electrodes and a saturatedhydrochloric acid solution of compounds of antimony and chlorin,preferably antimony trichlorid, as the electrolyte. By using these,equally good results may be ob- I tained regardless of any oneparticular de-' sign or construction of the cell, providing the generalrules and principles, pertaining to storage battery engineering, areobserved. Hence I do not limit myself to the precise construction,asillustrated in the accompanying drawing and herein following de-,scription thereof, wheiein- Figurel is a vertical section of the entirestorage cell, as indicated by the dotted line 0-0 in Fig.2, which is atop view of the cell; Fig. 3 is a cross section through the entire cell,as indicated by the dotted line B-B in Fig. 1;. Fig. 4: is a full sizesection of part of one of the twenty-four antimony plates P, thatconstitute the electrodes, showing that part which slides over theconnecting rods S or S, andpart of the grooved surface; Fig. 5 is across section of the cupshaped upperpart of the glass rod L, asindicated by the dotted line -A-A in Fig. 1.

The containing vessel 0 is made of glass, and has three circularcavities in the bottom 'to hold the two antimony connecting rods S S andthe glass rod L in place, as illustrated in Fig. l; the cover K is alsoof glass and firmly screwed to the containing vessel 0 by means of thesix bolts N.

' The twelve antimony plates, that constitute the positive electrode,are connected and held together in a horizontal position, by sliding oneabove the other onto the ant-imony rod S, interposed by the twelveantimony plates that constitute the similarly constructednegativeelectrode with the antimony rod S, as illustrated in Fig. 1; the glassrings R (marked in Fig. 3 only) separate the positive and negativeplates from each other, and also serve as supports for them. In thecenter, through the plates and rings, is placed the glass rod L, whichterminates at the top in a cup form, so as to permit the funnel-shapedextension in the center of the cover K to slide into it, thus holding itin place and preventing the plates and rings from shifting; J J Q I arerub;

ber bands.

The glass stopper F can be removed by releasing the brass spring G, forthe purpose of filling the cell with the electrolyte; the four holes M,as illustrated in Fig. 5, permit the liquid to pass through as indicatedby the two arrows in Fig. 1; the dotted line E-E indicates the properheight for the electrolyte.

The binding posts 1) D are of brass, and form the terminals of the cell;they are screwed to the antimony caps H H, into the two circular holesin the cover K; the antimony rods S S connect with the antimony caps H Hby sliding into them when the glass cover K is screwed in place, thusformmg complete connections, 'as' illustrated in I vFig. 1.

Each antimony plate is perforated with sixteen holes, as illustrated inFig. 3, to allow a more free circulation in the electrolyte. To offer agood surface for effective electrolytical action, the plates are groovedon both sides in a checkered manner, as illus- At the N egati've Plates.During charge: I it 7 Sb O 3H,:- ..2Sb 3H, Q 7
